Muhammad Ghori invaded India in 1175 AD. After the conquest of Multan and Punjab, he advanced towards Delhi. The brave Rajput chiefs of northern India headed by Prithvi Raj Chauhan defeated him in the First Battle of Terrain in 1191 AD. After about a year, Muhammad Ghori came again to avenge his defeat. A furious battle was fought again in Terrain in 1192 AD in which the Rajputs were defeated and Prithvi Raj Chauhan was captured and put to death. The Second Battle of Terrain , however, proved to be a decisive battle that laid the foundations of Muslim rule in northern India.
